Petunia plant named ‘SAKPET105’

ABSTRACT

A  Petunia  plant particularly distinguished by having burgundy and white star patterned flowers and a semi-trailing, and mounding habit, is disclosed.

Genus and species: Petunia hybrida.

Variety denomination: ‘SAKPET105’.

BACKGROUND OF THE NEW PLANT

The present invention comprises of a new and distinct cultivar ofPetunia, botanically known as Petunia hybrida, and hereinafter referredto by the cultivar name ‘SAKPET105.’ ‘SAKPET105’ characterized by havinga burgundy and white star pattern and mounding plant habit. ‘SAKPET105’originated from a hybridization in Kakegawa, Japan in 2013. The femaleparent was a proprietary Petunia breeding line named ‘2ExTr-111a-V1’(unpatented) having a rose star pattern and a semi-mounding plant habit.The male parent was a proprietary Petunia breeding line named‘2ExTr-111a-V2’ (unpatented) having a rose star pattern and asemi-mounding plant habit.

In June 2013, ‘2ExTr-111a-V1’ and ‘2ExTr-111a-V2’ were crossed inKakegawa, Japan and 300 seeds were obtained. In February 2014, the F₁seed was sown in the greenhouse, cultivated and 140 plants were producedwith flower colors of rose star pattern and rose with mounding,semi-mounding, and semi-creeping plant habits. In June 2014, five plantlines were selected within the F₁ plants that both had burgundy andwhite start pattern flowers and a mounding plant growth habit. Aselection named ‘L2015-PT032’ was selected from these plant lines. FromFebruary to March 2015, ‘L2015-PT032’ was evaluated for day lengthneutral flowering response. From March to May 2015, ‘L2015-PT032’ wasvegetatively propagated, cultivated and transplanted to the field foroutdoor evaluation. From June to October 2015, the final selections werechosen and the mother stock was established. In January 2016, thebreeder confirmed the line to be fixed and stable. The line wassubsequently named ‘SAKPET105’ and its unique characteristics were foundto reproduce true to type in successive generations of asexualpropagation.

-   Classification:    -   -   Family.—Solanaceae.        -   Botanical.—Petunia hybrida.        -   Common.—Petunia.        -   Designation.—‘SAKPET105’.-   Growth: Environmental conditions for plant growth: The terminal 1.0    to 1.5 inches of an actively growing stem was excised. The    vegetative cuttings were propagated for five to six weeks. The base    of the cuttings were dipped for 1 to 2 seconds in a 1:9 solution of    DIP 'N GROW (1 solution:9 water) root inducing solution immediately    prior to sticking into the cell trays. Cuttings were stuck into    plastic cell trays having 98 cells, and containing a moistened peat    moss-based growing medium. The cuttings were misted with water from    overhead for 10 seconds every 30 minutes until sufficient roots were    formed. Rooted cuttings were transplanted and grown in 20 cm    diameter plastic pots in a glass greenhouse located in Salinas,    Calif. Pots contained a peat moss-based growing medium. Soluble    fertilizer containing 20% nitrogen, 10% phosphorus and 20% potassium    was applied once a day or every other day by overhead irrigation.    Pots were top-dressed with a dry, slow release fertilizer containing    20% nitrogen, 10% phosphorus and 18% potassium. The typical average    air temperature was 24° C.-   Plant description:    -   -   Form.—Semi-trailing.        -   Habit.—Mounding and semi-trailing.        -   Height.—About 19.0 cm from soil line to the top of the            foliage.        -   Spread.—About 39.0 cm.        -   Number of branches.—6 main basal branches; many secondary            and tertiary branches.        -   Length of branches.—13.5 cm to 19.0 cm.        -   Diameter of branches.—3.0 mm.        -   Life cycle.—Annual; tender perennial in warm climates.        -   Time to produce a rooted cutting.—About 4 weeks.        -   Time to bloom from propagation.—6 to 8 weeks.        -   Flowering requirements (season).—Will flower so long as            temperature is above 13° C. and greater than 12 hours of            daylight.        -   Resistance and susceptibility to diseases and pests.—No            particular resistance or susceptibility observed.        -   Temperature tolerances.—No particular temperature tolerances            observed.-   Stems:    -   -   Stem color.—Closest to RHS 144B (Yellow-Green).        -   Anthocyanin color.—Absent.        -   Stem pubescence.—Heavy.        -   Stem pubescence color.—RHS N155A (White).        -   Stem description.—Pliable; circular shape in cross-section.        -   Length.—9.0 cm to 13.0 cm.        -   Diameter.—2.0 mm.        -   Internode length.—About 1.5 cm.-   Leaves:    -   -   Arrangement.—Alternate.        -   Shape.—Ovate.        -   Apex.—Obtuse.        -   Base.—Attenuate.        -   Attachment.—Sessile.        -   Margin.—Entire.        -   Surface appearance.—Dull, waxy and sticky.        -   Venation pattern.—Pinnate.        -   Venation color.—Upper vein color: RHS 147C (Yellow-Green).
